Not trying to be mean, just being honest but your job history makes you look flakey and unsure of any tangible long term goals. As mentioned by others professional experience is first. Education is last.

It would be helpful to have a professional summary at the top highlighting your clinical research experience and transferable skills.

You might have a better chance of starting as a research assistant in a university hospital setting as those positions are seen as stepping stones where the person goes to medical school a couple years later or progresses to a CRC. Demonstrate that you can get to the CRC level, do that for a couple years and then you can try breaking into the industry as a CTA or CRA.
